Baked haddock is light, flaky, and full of flavor. My easy oven-baked recipe is ready in just 20 minutes, making it a healthy and reliable weeknight dinner. Watch the video below to see how I make it in my kitchen.
Preheat the oven to 400°F (200°C). Prepare a 9x13-inch baking dish and set it aside.
Pat the haddock fillets dry and season with salt and pepper.
Add the tomatoes, olive oil, lemon, garlic, and thyme to a mixing bowl and whisk together. Add it to the baking dish. Place the haddock filets on top, pushing aside the tomatoes/lemons/garlic around them.
Bake for 15 minutes or until the fish is opaque and flaky, and reaches an internal temperature of 145°F.
Remove the baking dish from the oven and serve the fish immediately.
